- 摘要:
- 为了提升室内装饰用6063铝合金的表面性能，采用化学刻蚀、阳极氧化和表面修饰相结合的方法对6063铝合金基体进行了表面改性处理。对比分析了化学刻蚀时间（0、1、3和5 min）对表面改性膜层显微形貌、润湿性能和耐腐蚀性能的影响。结果表明，化学刻蚀处理后会在6063铝合金基体表面形成形状不规则、尺寸不等的腐蚀坑，化学刻蚀处理后6063铝合金试样的表面粗糙度和与水滴的接触角都有所增加，且化学刻蚀时间越长、表面粗糙度越大，化学刻蚀3 min后试样与水滴的接触角达到151 °。6063铝合金在化学刻蚀、阳极氧化和修饰处理后，十二氟庚基丙基三甲氧基硅烷已成功自组装到阳极氧化膜表面形成硅烷膜。极化曲线和电化学阻抗谱的测试结果保持一致，即相较于未经化学刻蚀的试样，经过化学刻蚀处理后再进行阳极氧化和表面修饰处理的试样的耐蚀性能都会有所提高，且经过3 min化学刻蚀试样的耐蚀性能最好，适宜在室内装饰用6063铝合金的表面改性中应用。
- Abstract:
- In order to improve the surface properties of 6063 aluminum alloy for indoor decoration, a combination of chemical etching, anodizing, and surface modification was used to modify the surface of the 6063 aluminum alloy substrate. The effects of chemical etching time (0, 1, 3, and 5 min) on the microstructure, wetting properties, and corrosion resistance of surface modified film layers were compared and analyzed. The results showed that irregular shaped and unevenly sized corrosion pits were formed on the surface of the 6063 aluminum alloy substrate after chemical etching treatment. The surface roughness and contact angle with water droplets of the 6063 aluminum alloy sample increased after chemical etching treatment, and the longer the chemical etching time, the greater the surface roughness. After 3 minutes of chemical etching, the contact angle between the sample and water droplets reached 151 °. After chemical etching, anodizing, and modification treatment, dodecafluoroheptylpropyltrimethoxysilane has successfully self-assembled onto the surface of the anodized film of 6063 aluminum alloy to form a silane film. The polarization curve and electrochemical impedance spectroscopy test results are consistent, indicating that compared to the sample without chemical etching, the corrosion resistance of the sample treated with chemical etching followed by anodizing and surface modification will be improved. Moreover, the corrosion resistance of the sample treated with 3 min of chemical etching is the best, making it suitable for surface modification of 6063 aluminum alloy for indoor decoration.
